London Residential Architect

Your home,
thoughtfully
transformed.

I'm Andrea — an architect based in London. I work with homeowners on extensions, loft conversions, listed buildings, and everything in between. I handle the planning, the drawings, and the complexity. You get to focus on what the space will actually feel like to live in.

Projects that speak
for themselves

Each project is different. Each is treated with the same rigour — from first sketch to completed building.

What We Do

The full service,
start to finish

Four stages, one point of contact. You tell me what you want. I handle the rest.

01
Design & Concept

I start by understanding how you actually live, not just how many rooms you need. You receive layout options, early sketches, and a design brief — so you can make confident decisions before spending a penny on builders or planning fees.

Space planning · Sketch proposals · Layout options · Design brief
02
Planning & Consent

Full planning permission, listed building consent, or permitted development confirmation — I manage the entire process. Drawings, documentation, council communications. None of it lands on your desk.

Planning applications · Listed building consent · PD confirmation · LBC
03
Technical Design

Fully detailed construction drawings covering structure, materials, lighting, finishes, and building regulations compliance. Good technical drawings mean accurate quotes and no surprises on site.

Construction drawings · Building regulations · Structural coordination
04
Construction Supervision

I stay involved throughout the build, working alongside your contractor to ensure the design is delivered. Problems get caught early. You have someone to call who knows the project inside out.

Site visits · Contractor liaison · Quality checks · Snagging
Specialist Areas

Where experience
makes the difference

Three areas where the wrong choice costs time and money. I know how these processes work from the inside.

Permitted Development

PD rights are not automatic. Article 4 directions, previous extensions, volume limits and conservation area restrictions can all invalidate a PD claim. I check everything before you spend a penny on construction.

Listed Buildings

Works to a listed building require Listed Building Consent where they would affect its character as a building of special architectural or historic interest. I know how conservation officers and Historic England think, and I prepare applications to their standards from day one.

Conservation Areas

Conservation area status can reduce or affect your permitted development rights and may influence decisions on materials, windows, roof lines, and boundary treatments. Planning permission may be required, with conservation area considerations applied. I know what councils in your borough will accept.

Client Feedback

What clients say

★★★★★

"Andrea understood immediately what we were trying to achieve — not just the rooms, but the feeling of the house. The planning application sailed through, and the builder said it was the clearest set of drawings he'd worked from in years."

Sarah & James T.
Rear extension & loft conversion, Wandsworth
★★★★★

"We have a listed building and had been told by two other architects it was too complicated. Andrea knew exactly what the conservation officer would want to see, and we got consent first time. I cannot recommend this practice enough."

Catherine M.
Listed building renovation, Lambeth
★★★★★

"What I valued most was the honesty. From the very first call, Andrea told us exactly what was possible and what was not. The project came in on time, within the budget we had agreed, and the result is genuinely beautiful."

About

I'm Andrea Maugeri — an architect based in London with over ten years of experience working on residential projects across the city.

I run this practice independently, alongside a role as Practice Director at a consultancy. That combination keeps me close to real projects — I'm not just advising, I'm designing, drawing, and on site.

I started working for myself because I wanted to be genuinely useful to homeowners — not just technically competent, but someone you can actually talk to. Most people I work with have never hired an architect before. My job is to make that process feel straightforward, not intimidating.

I work across London on extensions, loft conversions, listed buildings, and full refurbishments. I also run a podcast called Secrets Behind the Finishes — where I talk through the things people most want to understand before they start a project.

It depends on property type, size of works, and location. Many single-storey rear extensions fall within permitted development rights and do not require a planning application — but this is not automatic. Conservation areas, Article 4 directions, listed status, and the size of any previous extensions can all remove those rights. I can usually confirm your position within five working days — book a free call to discuss.
For a standard London loft conversion — including survey, planning drawings, building regulations drawings, and planning coordination — fees typically range from £1,500 to £5,000, depending on the complexity, level of detail required, and extent of coordination involved. I offer fixed-fee packages for most standard residential projects so you know exactly what you are paying before we start. Fees are discussed transparently at the first consultation with no surprises.
From first consultation to planning decision typically takes 4–6 months for a standard householder application (8 weeks for the formal decision, plus time for surveys, design, and drawings). Listed building consent can take longer. A permitted development certificate of lawfulness is usually 6–8 weeks from instruction to decision. I am transparent about timelines from the outset and I won't make unrealistic promises to win your business.
Conservation area status means planning permission may be required for works that would otherwise be permitted development. This can include rear extensions beyond certain sizes, roof alterations, and changes to windows and doors on principal elevations — though the specific restrictions depend on your borough and whether an Article 4 direction applies. It does not mean your project is impossible — it means the design and application need to be prepared carefully. I have extensive experience with conservation area applications across London boroughs.
Start by finding out the grade of listing (Grade I, II*, or II) and booking an initial call. Works that affect the character of a listed building as a building of special architectural or historic interest require Listed Building Consent — this can include internal as well as external works. Listed Building Consent is separate from planning permission; depending on the works, you may need one or both. The key is understanding the conservation officer's likely position before you prepare drawings, not after. I have direct experience with listed building applications and know how to prepare documentation that anticipates the statutory consultees' questions.
A drawing service gives you plans. An architect gives you a project. The distinction matters most when your property is listed or in a conservation area, the project involves structural complexity, or you want the design to be genuinely good rather than merely compliant. For most projects in London — with its complex planning environment, conservation areas, and heritage sensitivities — an ARB-registered architect reduces risk, adds design value, and can help avoid costly mistakes over the life of the project.
Podcast

Secrets Behind
the Finishes

I started Secrets Behind the Finishes because most people arrive at their first consultation having spent weeks reading contradictory things online. So I decided to say clearly what I know — how planning actually works, what things cost, what to watch out for, and when to be sceptical.

It's aimed at homeowners, not architects. No jargon. No sponsorship. Just honest conversations about the process of changing your home.
